MACHINE FOR DRESSI NG HOOPS.

SPECIFICATION forming part of Letters Patent No. 252,207, dated January10, 1882.

Application filed October 4,1881. (ModeL) To all whom it may concern:

Be it known that I, SAMUEL R. GARNER, of (Jassville, in the county ofGrant and State of Wisconsin,haveinvented certain new and usefnlImprovements in Machines for Dressing Hoops, of which the followingisaspecification.

My improvements relate to machines for dressing box-straps and barreland tierce hoops split from poles; and the invention consists in 1ocertain'novel features in the feeding mechanism, as .hereinafterdescribed and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicate cor-1 responding parts in all the figures.

In the drawings, Figurel is a side elevation of a hoop-machinecontaining my improvements, and Fig. 2 is a plan view of the machine.

A is the bed of the machine, supported on a suitable frame.

a is a shaft, sustained at the level of the bed by suitable bearings andprovided with a pulley, b, for connection of power.

13 is the cutter-head fixed on shaft a. i

o is a short shaft boxed on the lower part of the frame, and carrying apulley, d, from which a belt passes to a pulley on shaft (1.

-e is a vertical shaft operating the feed-rollers, as hereinafterdescribed, and driven from shaft 0 by gear-wheels, as shown, or by anysuitable connection. The feed is from one side of bed A parallel withshaft a.

The cutter-head is formed of a disk, 0/, having a cup-shaped flange, b,on which the cut- 3 5 ters f are attached ,with their cutting-edgesprojectin g into slots 9 formed in the flange. There are three cutters fshown but more or less may be used, as required, and they conform to thecurved form of the head, and are set at an o inclination to the axis ofthe head, so as to act with a slanting and gradually-deepening out.

On thebed A, next to the edge of head B,-is fixed a plate, h, havinga-raised edge, curved to the form of the cutter-head, for supporting 5the hoop in the required position.

The feeding mechanism is as follows: At the side of'bed A is hung a bentlever, i, on which is a loose roller, 70, grooved for engaging the edgeof the hoop. The lever is fitted at its outer end to receii'e a weight,and extends through a slotted guidepiece, l, fixed on the frame. on thebed A is a slide, 112, arranged to move in a grooveway to and from theface of head B, and carrying a vertical gage-roller, n, of rubber orfaced with rubber. A lever, o, pivoted on the bed and connected to slidem, extends in contact with lever t in such a manner that the weighttends to move slide m toward the cutters and press the roller n tothehoop passing through. Beyond the cutter-head are two vertically-placedfluted rollers, 10 10', one of which, p, is on the shaft 6, beforementioned, while the other roller, p, is on a fixed arbor. Theshaft eand the separate arbor are sustained at their upper ends by a bridge, q,and are connected for simultaneous movement by pinions r. The bedA isslotted for shaft 0 to pass, and a spring, 8, fixed beneath the bed andbearing on the shaft, serves to press the roller towardthe other andallow for variations in thickness of the finished hoop. The backwardmovement -of slide m is limited by a set-screw, t.

In operation the half-round hoop is entered on edge beneath roller k,and passes between the gage-roller n and cutter-head with, the bark sidenext to the roller, and then between the two rollers 10 p, which drawthe hoop forward. The weighted leveri presses the hoop downward, and byacting on lever o and roller a presses it up to the cutters, while thecurved plate It acts to retain the hoop edge up and properly presentedto the cutters. The rubber face of roller it allows knots to passwithout the effect of reducing the average thickness of the finishedhoop. The cutters f act first by their lower corners and edges to cutthe heart of the wood and'then finish to auniform thickness. As soon asthe last end of the hoop passes roller k the lever 'i, beingnnsustained, exerts its weight to press the gage-roller n iuo ward andthe hoop end to the cutters,with the effect to taper of'bevel off theend of the hoop as required for the lap. The shape of cutters aand theslanting cut obtained thereby prevent the removal of the wood in sliversthat 5 might choke the machine. At the same time the cut assists thefeed, so that the feed-rollers are not required to press so tightly asto strip the bark. The feed-rollers p are set on a line diagonally ofthe feed for the purpose of overcoming the natural bend of the hooptoward the bark side. The angular position of the 5 rollers tends topress the hoop toward the gageroller, and also to take the bend out ofthe finished hoop, so that they can be readily bundled. I am aware thata cutter-head made in disk form and having a flanged periphery is not tobroadly new, and I am also aware that an adjustable head-block has beenarranged directly in front of and adjustable feed-rollers at the side ofthe'cutter-head; but

What I claim, and desire to secure by Let- 15 ters Patent, is-

1. In a hoop dressing machine, the combination, With the grooved frame Aand the cutterhead B, of the slide m, the gage-roller n, the levero, andthe Weighted lever 45, substantially 20 as and for the purpose setforth.

2. In a hoop-dressing machine, the combinaroller 7r, mounted looselyonsaid weighted lever, 0

substantially as and for the purpose set forth.

4. In a hoop-dressing machine, the combina- 'tiou,withthei'ran1e A,provided with the guideplate h, and the cutter-head B, of the groovedpressure-roller k, the adjustable gageroller n, 5

and the adjustable fluted feed-rollers pp, substantially as and for thepurpose set forth.
